I must admit, I have become far less enamoured of Civ as I get older. I used to play it religiously, dating all the way back to the original. Then occasionally. Then I didn't play for years, before firing up BTS last year out of the blue. Whole reason I started lurking here, matter of fact. I quit playing again after a few weeks, because I just don't find it as fun as I used to. Part of that is the simplicity, and part of it is just a lack of motivation; I've won it many times before, I can usually tell if I'm going to win by Year 0, and I'm just not motivated enough to ekkeep playing beyond that. I could g up a difficulty setting, but at the higher levels it's as much mathematical as it is creative, and I'm playing games to relax, not for the challenge like some.
Same reason I gave up on EUIII; I just don't want to micromanage like that, and even if I did, I don't have that sort of spare time. I can steamroll mofos as England or France or Austria, but I just don't have the patience to play as anyone else for long.
So I guess I'm not casual enough for Civ, but too casual for Paradox? My gaming life sounds like my love life, when you put it that way.
